The book addresses molecular, cellular, behavioral and clinical roles for epigenetic mechanisms in the nervous system. Epigenetic changes are chemical reactions that turn our genes on and off during our lifespan – without changing the DNA code we inherited from our parents. One theory has it that such reactions represent the mechanism by which our neural networks store memories.

“Given the recent rapid pace of discovery in this new scientific sub-discipline, it was time to introduce a foundational book that will be broadly relevant to emerging research programs investigating the role of epigenetics in the nervous system,” said Sweatt. “This book is the first unified synthesis of information on molecular epigenetics, development, cellular physiology and biochemistry, plasticity and behavioral models.”

The book is primarily intended for advanced undergraduates, graduate students, active researchers and physician-scientists newly interested in the emerging field.

Sweatt is also responsible for the book’s extensive illustrations, which are copies of his paintings depicting the role of epigenetic processes in the brain, and relate to work under way in his lab. As an artist, Sweatt’s paintings reflect a central theme, he said: “the awesome complexity of the nervous system at all levels, from cognition to molecular genetics to everything in between.”
